Project History
Foss and Company Growth Marketing Consulting
- 3x — Increase in Monthly MQLs
- 20% — Decrease in Cost-per-lead
- 27 — Increased Domain Authority for SEO/GEO
Foss had a strong content marketing team and great sales development, but they were struggling to generate leads. They had run digital ads previously and done some basic SEO, but there was a lot of room for opportunity when I joined.
• Conducted a complete marketing audit to see where the strengths were, and what was low-hanging fruit.
• Fixed attribution to get a clearer sense of which channels were resulting in down-funnel leads and closes.
• Started gearing up technical SEO and backlinking when they had only done the content side in the past.
• Leveraged GEO tracking tools to determine which keywords were most opportune to target.
• Optimized Google Ad campaigns and launched LinkedIn ads to capitalize on gated whitepaper content.
• Saw monthly MQLs increase by over 3x cross-channel, including nearly 4x from organic (SEO/GEO).
• Large increase in Domain Authority (27 points in 6 months) led to better rankings and visibility.
• Leads became 20% more efficient on ad channels.
Talkiatry Marketing
http://talkiatry.comHeaded growth marketing for Talkiatry during a pivotal time of expansion for the company.
As the marketing lead, I owned Google Ads, Meta Ads, Bing Ads, and SEO channels for lead generation. I also increased lead volumes by three times in the first month, continuing growth over the next half year while decreasing costs per lead.
This demand generation helped Talkiatry expand to six new states and build brand awareness that enabled them to recruit more psychiatrists to the platform (growing supply side as well).
EarnUp
http://earnup.comServed as the growth marketing lead for fintech startup to grow their online presence, develop their brand for both B2C and B2B2C, and drive demand.
I worked with EarnUp’s CMO to drive growth during the company’s fundraising period. I led Google Ads, Meta Ads, and SEO channels to acquire new customers. We saw 2.5 times monthly signup growth and over two times monthly subscriber growth while keeping budgets static.
I also owned the creative strategy, conversion rate optimization (CRO), funnel optimization, and audience refinement. I revised the targeting strategy to a different audience segment that proved more engaged and a source of deeper funnel leads.
Finally, I helped the company raise its next round of funding due to strong lead generation and revenue metrics attained.
Merry People Interim CMO
Spearheaded the burgeoning Merry People marketing team with go-to-market (GTM) strategy in the US.
Merry People is a fashionable rain boot and gumboot startup in Australia. I worked as their CMO when their CEO was going on leave. I was entrusted with managing the marketing team and agency partners and driving the brand’s strategic expansion into the US. As part of my six months there, I:
• Led an overhaul of non-brand marketing strategy.
• Assisted with the marketing platform expansion to uncover successful lead generation channels.
• Drove record sales during their peak season and the start of their low season (when my project ended).
• Oversaw the strategy for their US (primary focus), NZ, and UK expansion efforts, helping manage budgets and demand and adjusting for supply and manufacturing challenges.
